Ever since the relink window was introduced the size adjustment has been awkward. Always the first frame edge to be adjusted is the one below the "select area to search" because it never will show all the drives etc. needed for pointing to. Grabbing that lower frame edge results in its resize, BUT only to the edge of the next lower frame edge where it is forced to stop. So then that next lower one needs to be moved, before adjusting the first one a SECOND TIME. It's a frustrating use of editing time to be doing this. The solution is to have the first window push the second if that is what the user needs to see more in the first window.
